Flow or Leveling

When the paint does not dry to a smooth film after application, it results in brush and roller marks on the surface. This condition is Flow or Levelling and this defect is often unpleasant.

Possible Causes


Paint is too heavy • Reduce the viscosity of the paint and get the correct consistency.
• Check for correct viscosity using Zahn #2 viscosity cup.
Faster Evaporation of the Solvent Use solvents that evaporate slower, if the air temperature is higher.
Improper Air Atomization Adjust the spray gun
Application of paint on Thin Surfaces Apply paint on surfaces with more passes. Let the application be wet immediately.
Increase in Air Movement Reduce the draft
